2007 Lancia Thesis wheel bolts

274
Signal the presence of
the stopped car according
to the laws in force: haz-
ard lights, reflecting triangle, etc.
Passengers should get out of the
car and stay clear from oncoming
traffic while the wheel is being
changed.
IF A TYRE
IS PUNCTURED
Follow the instructions on this and
the following pages to use the jack
and the spare wheel correctly.If the wheel is being
changed on a steep or
badly surfaced road,
place wedges or other suitable
material under the wheels to stop
the car from moving.
Have the punctured tyre
repaired and fitted back as soon
as possible. Do not lubricate the
bolt threads before fitting them
back: they could come loose.
Wheel bolts are specific
for the type of rim (alloy
or steel) fitted. Never use,
also if in an emergency, wheel
bolts for another type of rim.
When changing rims (alloy rims
instead of steel ones or vice
versa), also the whole wheel bolt
set shall be changed with other
bolts specific for the new type of
rim adopted.The jack should only be
used to change a wheel on
the car for which it was
designed. It should not be put to
other uses or employed to raise
other models of car. Under no
circumstances should it be used
when carrying out repairs under
the car.
An incorrectly positioned jack
may cause the car to fall.
Do not use the jack to lift loads
exceeding those indicated on the
label attached to the jack itself.
The wheel cap may fly off when
the car is moving if it is not fas-
tened correctly. Never tamper
with the inflation valve. Do not
insert tools between the rim and
the tyre.
Check the tyre and spare wheel
pressure regularly. Tyre pressure
is shown in the “Technical
Specifications” chapter.

8) Unscrew manually the jack han-
dle A(fig. 7) and remove it from the
container B.9) Open the tool bag and take out
the tools to be used (fig. 8):
1 – tow ring
2 – flat/cross-head screwdriver
3 – ratchet wrench
4 – ratchet wrench bush
5 – wheel bolt (for versions with
alloy rims)
6 – tool for removing the hub cap
(for versions with alloy rims)
7 – bush for unscrewing/screwing
the wheel bolts by hand8 – wrench for power steering re-
servoir cap screws
9 – wrench for actuating the sun-
roof in an emergency (where fitted)
10) On versions with alloy rims,
remove the press-fit wheel hub cap
A(fig. 9), pulling it by tool Bfitted
into C. On versions with steel rims,
remove the press-fit wheel cap A
(fig. 10).

13) Position the jack under the car
near the wheel to be replaced in the
point shown on the panelling at
approximately 20 cm from the fend-
er edge, as shown in (fig. 12). 11) Place the bushing A(fig. 11)
for the wheel bolts on the ratchet
wrench B.
IMPORTANTThe ratchet wrench
must be used on one side to unscrew
and on the other side to screw.
12) Loosen the wheel bolts by
about one turn, then rock the car to
make it easier to remove the rim
from the wheel hub.Warn anyone nearby
that the car is about to be
lifted. They must stay
clear and not touch the car until
it is back on the ground.

15) Insert the ratchet wrench A
(fig. 14) with the bolt bush Bon the
jack groove.
IMPORTANTThe ratchet wrench
must be used on one side to unscrew
and on the other side to screw.
16) Turn the jack handle and lift
the car until the tyre is a few cen-
timetres off the ground.17) Loosen the wheel bolts and
remove the wheel.
IMPORTANTTo make this opera-
tion easier, use the proper bolt bush
A(fig. 15).
18) Make sure the surfaces of the
spare wheel that come into contact
with the hub are clean and free from
any impurities which could result in
the wheel bolts working loose.

14) Turn the jack handle A
(fig. 13) by hand so to open it par-
tially and position the jack under the
car.
Turn the jack handle until the jack
groove Bfits onto the bottom edge C
of the underbody correctly.

19) On versions with alloy rims, to
make the wheel fitting easier, screw
the pin A(fig. 16), provided in the
tool kit, to the hub and then place
the wheel and tighten up the four
bolts in the free holes. Finally,
unscrew pin Aand screw the last
bolt.
On versions with steel rims, fit the
wheel making pin A(fig. 17) coin-
cide with one of the holes B.
IMPORTANTTo make bolt tight-
ening easier, use the proper bolt
bush A(fig. 15).Wheel bolts are specific
for the type of rim (alloy
or steel) fitted. Never use,
also if in an emergency, wheel
bolts for another type of rim.
When changing rims (alloy rims
instead of steel ones or vice
versa), also the whole wheel bolt
set shall be changed with other
bolts specific for the new type of
rim adopted.20) Lower the car and remove the
jack (fig. 18).

Bolt tightening torque
must be 98 Nm (10 kgm).
After replacing the
wheel, you are advised to have
the wheel bolt tightening checked
at a Lancia Dealership as soon as
possible.
Insufficient tightening could
actually make the wheel bolts
loosen too much, with clearly
dangerous consequences. If the
bolts are tightened too much, they
could be damaged and their
resistance might be compro-
mised.23) Place the removed wheel, the
jack and the tools in the boot and
fasten appropriately.
IMPORTANTPut the jack back
into B(fig. 8) and clamp it by
screwing handle A(fig. 8) manually
in order to prevent vibrations during
travelling.

21) Tighten up the wheel bolts in a
criss-cross fashion, following the
sequence shown:
- fig. 19= versions with alloy rims
- fig. 20= versions with steel rims.
22) On versions with alloy rims,
refit the wheel hub cap pressing it
slightly. On versions with steel rims,
approach the wheel cap making the
inflating valve A(fig. 21) coincide
with flaring B. Press the cap circum-
ference starting near the inflating
valve and proceeding until fitting
the cap completely.
IMPORTANTThe wheel hub cap
(alloy rims) or the wheel cap (steel
rims) may fly off when the car is
moving if it is not fastened correctly.
